Etiopathogenetic aspects of the use of probiotics in obese and overweight patients

In recent decades, obesity and overweight have become one of the significant problems of global public health. The steady growth of morbidity, development of complications and comorbid conditions, disability and an increase in mortality in obese patients indicate the need to develop new methods of treatment and prevention of this disease. It has been proven that some probiotics contribute to weight loss. The review presents an analysis of data from modern domestic and foreign studies concerning the use of certain bacterial strains in obese and overweight people for preventive and therapeutic purposes. Both classic probiotics with anorexigenic effect (Bifidobacterium spp., Lactobacillus spp., Saccharomyces boulardii) and next-generation ones (Akkermansia muciniphila, Enterococcus spp., Faecalibacterium prausnitzii, Bacteroides spp., Streptococcus spp., Eubacterium rectale, Blautia spp., Christensenella minuta) are considered. The main pathogenetic aspects of weight loss when using these probiotics (reduced permeability and enhanced protective functions of the intestinal epithelium, effects on the gut microbiome, anti-inflammatory activity) are described.
